Kerk Motion Products, one of the world's leading manufacturer's of non-ball lead screws, offers a full range of anti-backlash, non-ball lead screw assemblies utilizing Kerk's patented axial take-up mechanism. It continually compensates for wear while maintaining low frictional drag torque and high axial stiffness, delivering exceptional positional repeatability. Kerk lead screws are available in self-compensating/zero backlash, special purpose, and mini styles for a wide variety of applications and industries. Also available with Kerk's exclusive Kerkote® TFE soft coating, they deliver long life at an affordable cost while maintaining superior performance and reliability.

• Kerk's ZBX Series anti-backlash assembly for light loads is an ideal linear actuator for design operations which require precise positional accuracy and repeatability at a minimum cost.

• Kerk's KHD Series anti-backlash assembly is a linear actuator for moderate load design operations. Although the KHD offers high axial stiffness, frictional drag torque (1-3 oz.in.) is very low. The anti-backlash mechanism in the KHD unit eliminates the need for load compensating preload forces.

• Kerk's VHD Series for heavy loads is ideal for eliminating drag and wear associated with high pre-load forces. It provides the maximum load-carrying capability and the highest axial and radial stiffness of any Kerk nut assembly.

• Kerk's NTB Series is a full range anti-backlash lead screw assembly with a simple, compact design that is easily modified for custom applications. The NTB assembly provides low drag torque, high system stiffness, smooth operation, and long life throughout its load and speed range.

• Kerk's ZBA Series special purpose anti-backlash lead screw assembly features ultra smooth travel for applications requiring precise positional accuracy. The ZBA provides the ability to adjust the drag torque setting to match the specific requirements of applications also requiring noise or vibration control.

• Kerk's patented NTG Series special purpose lead screw assembly offers a cost effective anti-backlash solution for applications requiring precise positional accuracy, repeatability, and smoothness in a compact size. Like Kerk's ZBA series, the NTG Series provides the ability to manually adjust the drag torque setting.

• Kerk's MINI anti-backlash lead screw assemblies are available in both the NTB and NTG styles, bringing Kerk quality, precision and value to products that were previously off-limits to lead screw technology.

• All Kerk anti-backlash lead screws are available with Kerkote® TFE, Kerk's exclusive soft TFE coating that extends the life of the components and assemblies while maintaining superior performance and reliability.
